Application filed February 9,1911. Serial so; 007,457.

To all whom it may concern Be it known that I, MORRIS Scnosnrnnu, a citizen of the United States, and a resident of Rorschach, in the Canton of S t. Gall, Switzerland, have invented certain new and useful Improvements in Apparatus for Winding Stri of Embroidery 1n Layers, of which the ollowing is a specification.

The object of the present invention to provide a simple apparatus for winding strips of embroidery in layers, lying side by side upon a winding board, reel or drum or other holding means.

When embroidery is made in long strips to be sold in such strips it is usually wound upon a flat board of card or wood and this retains therembroidery in smooth condition while assin through the various channels of tra e until the embroidery is finally sold over the counter to the consumer, when various lengths are cut off and sold.

The object of my present invention is to wind the embroidery upon the holding means, whether the latter be a fiat board or other form of device, so that the embroidery will lie in rows side by side, the entire strip of embroidery being wound in helical form around the winding board.

One of the principal adavantages of the present invention is that handling of theembroidery may be avoided. The embroidcry can be fed directly from the machine which trims the embroidery, direct to mv' prcsentmachine, so that there will be no iiitermediate handling of the embroidery. I therefore prefer to make the present machine in such a way that the windin board will be,moved laterally as it'is revo ved, so that the embroidery may be fedfrom a given place, say from the machine above referred to, and still be wound in separate. turns on the winding board.

The present machine is'very simple and rapid in its operation and it winds the embroidery very smooth andeven and may be adjusted to operate with boards of various sizes and to wind embroidery of differentwidths.

In the drawingsforming a part of this application, .Figure 1 is an elevation of my improved machine, Fig.- section thereof taken on the 1, looking downward. Fig. of the chuck for holding the winding board, Fig. 4 is a section, taken on the line 4-4 of Fig. 1, looking in the direction of the arline 22 of Fig.

moving longitudinally 2 is a horizontal 3 is a plan view rows, and Fig. 5 is a sectional view taken ,on the line 5-5 of Fig. 1.

In Figs. 1 and 2 a three armed standard is represented at 1, in which is jonriialed a horizontalshaft 2. This shaft rotatable but is also longitudinally movable and is provided with a, on'gitudinal groove 4. Between the bearings 5 and 6' of the standard 1 is located a friction clutch consisting of a cone and disk 8, and 9, and between the bearings 6 and 7 is locatedabevel is not only.

gear 10, on the shaft 2. While the clutch disk 8 is loose on shaft 2, the clutch cone 9 and the bevel gear 10 are each provided with a key 47, which. enga the shaft 2, so that t e parts 9 and ,10 are caused to rotate with the shaft 2. In order to' prevent lateral movement of the parts'a) and 10 with the lateral movement of the an annular secured to the bearing 6, by a. screw 48, en-

gages. Between the bearing 5 and the clutch dislirl 8, a coil spring 13. surrounds the shaft 2, t

disk 8,- which also forms thedriving pulley e purpose of which is to force the clutch sinthegnoove tof for the shaft, against the clutch cone 9 whereby the shaft 2 and the parts connected thereto are driven. Withthe bevel gear 10 meshes a similar gear 14, secured to a vertical shaft 15. This shaft is prevented from I by reason of the wheel 14 and a collar 17, secured to said shaft, engaging opposite'sides of a'bearing 16 formed in the. standard 1. The shaft'15 is supported at one end in the bearing 16 and at the other end in a bearing. .18, secured to the foot of the standard 1. The shaft 15 is also provided with a longitudinal groove 19, anda roller 20 mounted on said shaft, has a key 49 enga 'said t-udinally on the shaft, 15. The hub of the roller 20 is provided with an annular groove 21, in which engages the forked end of an arm 22 projecting from a nut 24,- carried by a screw spindle 23. The spindle 23 is journaled in bearings 25 and 26, and is prevented from longitudinal movement by 'a hand wheel27 and-a collar 28, engaging opposite sides of the bearing 25. An arm 29,

rojecti from the standard 1 carries a hearing ir a shaft 30, to which is secured at one end a friction disk 31 and at the other end a crank disk 32. The friction disk 31 presses tightly against the driving roller 20,

groove, so that said roller can move ongi- 76 shaft 2, each of said parts is provided with groove 11, in 'which a yoke 12,

whereby the shaft 30 is rotated therefrom. In a diamet-ral dove tail roove 33, formed in the crank disk-32, is slidably mounted a block 34, (Fig. 4%) in which 1s screwed a bolt 34. 'On this olt is mounted a box 35,

' through which by tightening said bolt, the

block 3% is secured in adjusted position in the groove 33. On the box 35 is rotatably mounted the eye of a connecting rod 36, which is connected at its other end to an oscillatin lever 37. The latter has its pivot at 38 an is slotted at its upper end to enage the lateral pins 40,'pro ecting from a oose ring 41, mounted between the flanges of a collar 39, secured to the shaft 2.

The opposite end of the shaft 2 carries, by means of a chuck 43, (Figs. 1 and 3), a reel 44 for the winding of the strips'of embroidery. The clutch 43, consisting of a hub and two arms, is provided ith two "it''- shaped angles 45, which are riveted to the outer ends of said arms 43. To the ends of the stems of the angles 45 are secured two flat springs 46, between which the reel dcdt,

which consists generally of a Hat sheet. of

card board or wood, islremovably held by the clamping action of the springs.

By the rotation of the shaft 2, the reel 44 is driven directl and is also given an axial transverse disp acement in reverse directionsthrough the combined operation of the driving members 10, 14;, 15, 20, 31, 30, 32, 36 and3', the relative proportions of these members being such t at, for each complete rotation of the shaft 2, and the reel 44, the latter is moved axiall for a distance slightly greater than t e width of the strips of embroider so that such strips, delivered from a machine to the reel are wound u on the latter in helical coils lying side by side. Since the strips of embroidery are of various widths, the mechanism for moving the reel axially (consisting principally of the elements 15, 20 and 31) are so constructed and arranged that the movements of the oscillating lever 37 can be adjusted for various widths of strips. For this reason the driving roller 20 is adjustable by means of the screw spindle 23 toward and away from the center of the disk 31. In all cases it is necessary to so adjust these parts that, when the reel is covered with one layer consisting of a certain number of adjacent coils the crank disk 32 will have just made a half revolution and the shaft 2 with the reel will have moved its entire axial distancein one direction, whereupon by further rotation of the shaft 2, it will be moved longitudinally in the opposite direction, so as to allow the instants stain of embroidery to be wound upon the rec in a new layer. I

lltwill be apparent that adjustment m be made for every requirement and thong the embroidery comes from a definite fixed place, the same'is properly disposed on the winding board or feel. Various changes may be made in the construction of the machine without departing from the spirit of my invention, but I deem the machine herein shown, to be the best embodimentof my invention.
